Please can someone let me know the specs of a Oric Atmos PSU, as I need to buy a replacement and I do not have the one I was using anymore.

I sent my Oric Atmos to someone to do a modification and he sent me back the Oric Atmos unmodified and missing the power supply and does not seem likely I will get it back.

From what I have read here the PSU (when used with Cumulus) needs to be a least 1.2A and 9V. Does anyone know the connector tip size (I am guessing it is 5.5mm x 2.1mm) and the Polarity of the plug please?

On Muso's Oric Site you can find some pictures of Oric PSU's. On the labels are the specs: Output DC 9V, 5.4 VA (or ~600mA).
This is the standard Oric PSU, but it's really recommended to use PSU with 1.0-1.2A output when using Cumulus (or other periphery powered trough the expansion port).
Connector is 5.5mm x 2.5mm, but larger one can be used too important is the internal diameter.
Polarity is '+' inside, '-' outside.

Can someone here help me? I have not used my Oric Atmos for a few years now, and yesterday when I wanted to use it again, the power supply was missing. Anyone who can sell me a spare one? I want to use it with my Cumulus unit, so I guess from reading the above, that I should use one with a 1.0-1.2A output. Also, I want to use it with the RGB (Powered) Scart cable from Retro Computer Shack - http://www.ebay.co.uk/itm/Oric-1-amp-At ... 1137727260 – I do not know if this matters to power supply I seek?
